Hi Shawn,
The imx6sx-sdb board has two revisions, the current mainline is the
reva which is used by internal user mainly, and the revb is used widely
for internal and external users.
The main changes between reva and revb board:
- cpu operating point and related voltage
- pfuse
- qspi
- can transceiver (not mainlined)

As i.MX6SX SDB Rev-B board uses PFuse 200 which has only one power supply for both VDDARM_IN and VDDSOC_IN, so it needs VDDARM_IN equal VDDSOC_IN, currently we set Rev-B board as default in imx6sx.dtsi, which uses same voltage for both VDDARM_IN and VDDSOC_IN.The Rev-A board uses PFuze 100 which has separate power supply for VDDARM_IN and VDDSOC_IN, so it can use different voltage on VDDARM_IN and VDDSOC_IN according to datasheet.

Thanks for the clarification, Anson. Peter, OPP is a CPU characteristic defined by data sheet, so we should define OPP according to data sheet in imx6sx.dtsi, and only overwrite the property in Rev-B dts per board/PMIC quirk. Also, please put the rationale why we need OPP quick on Rev-B into commit log. Shawn ^ permalink raw reply [flat|nested] 14+ messages in thread
